Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an auxiliary device for semen dilution. Background Technology

[0002] In assisted reproductive technology (ART) embryology laboratories, semen optimization is a crucial step. Processed semen can be used in artificial insemination or in-vitro fertilization (IVF). When a man collects semen through masturbation, the semen is diluted, especially for non-liquefied semen, to promote liquefaction. This is typically done manually with a pipette, constantly blowing and stirring, while adding semen diluents and other reagents to increase semen volume, promote liquefaction, provide nutrients, and prolong sperm survival. However, the following problems currently exist in the male semen dilution process:

[0003] The current process of diluting male semen involves pouring the diluted solution into a collection cup and then manually stirring it with a glass rod or blowing it with a pipette. This process is inefficient, and it is difficult to control the stirring force when stirring manually. Excessive force can damage the sperm, while insufficient force can lead to incomplete mixing and is also time-consuming and laborious.

[0004] It is difficult to control the amount of diluent poured in manually, and it is easy to pour in too much or too little when pouring, so that the semen does not meet the dilution requirements;

[0005] During the process of diluting male semen, a large temperature difference between the mixed semen and the diluent can seriously affect the sperm motility after dilution. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides the following technical solution:

[0007] An auxiliary device for semen dilution includes a housing, a dilution tank, an air pump, and a semen collection cup. A stirring electric actuator, a dilution electric actuator, and a heating base are fixedly installed at the bottom of the housing. The semen collection cup is detachably mounted on the heating base. A stirring motor is fixedly installed at the upper end of the stirring electric actuator, corresponding to the position of the heating base. An adjusting block is fixedly installed on the drive shaft of the stirring motor, and a fixed head is slidably mounted on the adjusting block. A blow rod is detachably mounted on the fixed head, and an air pipe is installed on the fixed head, connecting the fixed head and the air pump. The stirring motor drives the blow rod to agitate, and the distance between the blow rod and the stirring motor can be adjusted by sliding the fixed head, thereby adjusting the agitation range of the blow rod. Airflow is delivered to the blow rod by the air pump.

[0008] A dilution arm is slidably mounted above the heating base inside the chamber. The dilution arm includes a sliding rod, a rotating rod, and a control rod. The rear end of the sliding rod is slidably connected to the chamber, and the front end is rotatably connected to the rotating rod. An elastic element is installed inside the chamber and connected to the sliding rod. The control rod is movably connected to the sliding rod, and its two ends are rotatably connected to the dilution electric push rod and the rotating rod, respectively. The contraction of the dilution electric push rod drives the control rod to move down and rotate, controlling the rotating rod to rotate and unfold. The dilution electric push rod continues to contract, pressing down on the sliding rod to slide, thereby driving the rotating rod to approach the semen collection cup.

[0009] Furthermore, a dilution conduit is fixedly installed on the rotating rod, the dilution conduit is connected to the dilution tank, and a metering pump is installed on the dilution tank to control the flow rate of the dilution conduit. A heater is installed inside the dilution tank.

[0010] Furthermore, the lower end of the fixed head is provided with several elastic flaps, and a fixing ring is threaded onto the lower end of the fixed head. The blow rod is slidably inserted into the fixed head, and the elastic flaps are contracted and clamped by rotating the fixing ring. An insert plate is fixedly provided on the side wall of the fixed head. The insert plate is slidably inserted into the adjusting block, and bolts are installed on the adjusting block to restrict the sliding of the insert plate.

[0011] Furthermore, an operating opening is provided on the box body, and a door panel is rotatably installed on the box body to cover the operating opening. One side of the door panel is rotatably connected to the box body, and magnetic strips are provided on the four sides of the door panel. The door panel is attracted to the box body by the magnetic strips to cover the operating opening.

[0012] Furthermore, electric push rods are fixedly clamped on both sides of the heating base at the bottom of the box body. Clamping plates are fixedly installed at the extended ends of the electric push rods. The clamping plates move and clamp the semen collection cup on the heating base by extending and retracting the electric push rods.

[0013] Furthermore, a connecting block is slidably mounted on the sliding rod, and a connecting sleeve is rotatably mounted on the connecting block, through which the control rod slides.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This invention features a dilution electric push rod fixedly installed inside a housing, and a dilution arm slidably mounted on the inner wall of the housing. In use, the semen collection cup is placed on a heating base and held in place by the clamping electric push rod. The contraction of the dilution electric push rod causes the control rod of the dilution arm to move downwards and rotate, controlling the rotation of the rotating rod. The continued contraction of the dilution electric push rod presses down the sliding rod, compressing the elastic element, thereby causing the dilution guide tube on the rotating rod to approach the semen collection cup. A metering pump on the dilution tank precisely controls the addition of diluent to the semen collection cup. A stirring electric push rod is also fixedly installed inside the housing. An adjusting block is fixedly mounted on the stirring motor drive shaft at the upper end of the stirring electric push rod, and a fixed head is slidably mounted on the adjusting block. A blower is mounted on the fixed head, and the stirring motor drives the blower to agitate the semen in the collection cup. The distance between the blower and the stirring motor can be adjusted by sliding the fixed head, thus adjusting the agitation range of the blower. An air pump delivers airflow to the blower, achieving automatic agitation and blowing of the semen, improving the efficiency and effectiveness of semen dilution.

[0016] This invention features a heater inside the dilution tank, which heats the diluent within the tank. Combined with the heating base, this heats the semen collection cup, maintaining the temperature of the semen and diluent in the cup at approximately 37°C. This reduces the temperature difference between the two and effectively preserves the sperm motility after dilution. Attached Figure Description

A blow rod 7 is detachably installed on the fixed head 602. An air pipe is provided on the fixed head 602, and the fixed head 602 and the air pump 102 are connected through the air pipe.

[0025] In this embodiment, the fixing head 602 is an existing clamping and fixing device. The lower end of the fixing head 602 is provided with several elastic flaps, and a fixing ring 6021 is threaded onto the lower end of the fixing head 602. The lower end of the fixing ring 6021 gradually narrows, and the lower end of the elastic flaps gradually flattens. The blow rod 7 is slidably inserted into the fixing head 6021. By rotating the fixing ring 6021, the elastic flaps are controlled to contract and clamp the blow rod 7. An insert plate 6022 is fixedly provided on the side wall of the fixing head 602. The insert plate 6022 is slidably inserted into the adjusting block 601, and bolts are installed on the adjusting block 601 to limit the sliding of the insert plate 601.

[0026] In this embodiment, a stirring electric push rod 2 is fixedly installed inside the housing 1. An adjusting block 601 is fixedly installed on the drive shaft of the stirring motor 6 at the upper end of the stirring electric push rod 2. A fixing head 602 is slidably installed on the adjusting block 601. A blow rod 7 is installed on the fixing head 602. The stirring electric push rod 2 retracts, causing the blow rod 7 to slide downwards and insert into the semen collection cup 8. The stirring motor 6 drives the blow rod 7 to stir the semen in the semen collection cup 8. The distance between the blow rod 7 and the stirring motor 6 can be adjusted by sliding the fixing head 602, thereby adjusting the stirring range of the blow rod 7. An air pump 102 delivers airflow to the blow rod 7 to blow air, thereby realizing automatic stirring and blowing of semen, improving the efficiency and effect of semen dilution. Example 2

[0027] Please see Figure 1-5According to Embodiment 1, a dilution arm 5 is slidably arranged above the heating base 9 inside the housing 1. The dilution arm 5 includes a sliding rod 501, a rotating rod 502, and a control rod 503.

The two ends of the control rod 503 are rotatably connected to the dilution electric push rod 3 and the rotating rod 502, respectively. The control rod 503 moves downward and rotates as the dilution electric push rod 3 retracts, controlling the rotating rod 502 to rotate and unfold. The dilution electric push rod 3 continues to retract, pressing down the sliding rod 501 to slide, thereby causing the rotating rod 502 to approach the semen collection cup 8.

[0028] In this embodiment, a dilution conduit is fixedly installed on the rotating rod 501, the dilution conduit is connected to the dilution tank 101, and a metering pump 105 is installed on the dilution tank 101.

The control rod 503 slides through the connecting sleeve.

[0029] In this embodiment, during use, the contraction of the dilution electric push rod 3 drives the control rod 503 to move downward and rotate, controlling the rotation rod 502 to rotate and unfold (at this time, the sliding rod 501 acts as an elastic element, and the control rod 503 is pressed down first when the dilution electric push rod 3 contracts). The dilution electric push rod 3 continues to contract, pressing down the sliding rod 501 to slide and compress the elastic element, thereby driving the dilution conduit on the rotation rod 502 to come close to the semen collection cup 8. Through the quantitative pump 105 set on the dilution tank 101, the diluent in the dilution tank 101 is quantitatively controlled to be added into the semen collection cup 8, thereby achieving precise control of the addition of diluent.
